Abstract： The widths for pionic decays of the lowest two excited doublets (0+, 1+) and (1+, 2+) of heavy mesons are studied with quantum Chromodynamics sum rules in the heavy quark effective theory. The interpolating currents used allow us to distinguish the two 1+ states without contamination in the infinite mass limit. The soft pion approximation is not used in the calculations.
